I came across something in The Sacred Tarot by C.C. Zain (that Church of Light book I mentioned the other day)
…The truly scientific man does not hold what he discovers, or what others have discovered, merely to benefit a chosen few… It has always seemed to me a colossal piece of selfishness for any group of men, if they really possessed information that might be beneficial to all mankind, to hoard it for themselves alone.
I hold, therefore, that secrecy in any matter that will aid the soul in gaining knowledge of its true relations to the universe, or will assist in making life happier, or the attainment of spirituality easier, is not a virtue.
Something to think about the next time you come across someone wanting to offer you a course in “magical secrets” for $1000.
